Abstract
Abstract Graphene is one of most exceptional type of nanocarbon. It is a two-dimensional, one atom thick, nanosheet of sp2 hybridized carbon atoms. Graphene has been employed as nanofiller for shape memory polymeric nanocomposites due to outstanding electrical conductivity, mechanical strength, flexibility, and thermal stability characteristics. Consequently, graphene nanostructures have been reinforced in the polymer matrices to attain superior structural, physical, and shape recovery properties. This review basically addresses the important class of shape memory polymer (SMP)/graphene nanocomposites. This assessment is revolutionary to portray the scientific development and advancement in the field of polymer and graphene-based shape memory nanocomposites. In SMP/graphene nanocomposites, polymer shape has been fixed at above transition temperature and then converted to memorized shape through desired external stimuli. Presence of graphene has caused fast switching of temporary shape to original shape in polymer/graphene nanocomposites. In this regard, better graphene dispersion, interactions between matrix-nanofiller, and well-matched interface formation leading to high performance stimuli-responsive graphene derived nanocomposites, have been described. Incidentally, the fabrication, properties, actuation ways, and relevance of the SMP/graphene nanocomposite have been discussed here. The potential applications of these materials have been perceived for the aerospace/automotive components, self-healing nanocomposites, textiles, civil engineering, and biomaterials.

Summary
Abstract: Graphene is one of most exceptional type of nanocarbon. It is a two-dimensional, one atom thick, nanosheet of sp[2] hybridized carbon atoms. High-performance epoxy-derived SMPs have been stated (51,52) These polymers are thermo-responsive (53), electro-active (54), light-active (55), pH sensitive (56), and moisture sensitive (57). The carbon nanoparticles have been used to supplement the electro-active and thermo-responsive effects (62) In this regard, the homogeneous nanofiller dispersion is a challenging factor to develop the high-performance shape memory materials. The allyl isocyanate-modified graphene formed better compatibility with the polyurethane matrix to enhance the mechanical and shape memory properties of the nanocomposites (104). The polyurethane/graphene nanocomposite with 3 wt% nanofiller loading showed 100% shape recovery during the thermo-responsive and electro-active actuations. The hydroxyethyl cellulose/GO nanocomposites showed moisture active behavior within 14 s Such natural polymer-based shape memory materials have been applied in water responsive sensors, actuators, and biomedical devices (131,132). Among frequently used thermosetting and thermoplastic polymers are epoxies, polyurethanes, PMMA, polyamides, and PS
